PIMELIAD.E TENEBRIONIDiE. 23,3 



DESCRIPTION. 



Body dull-black, oblong, naked. Head minutely punctured ; antenna? sborter tban tbe prothorax : 

 prothorax widest in the middle, subquadrangular with the sides rounded, minutely but not very 

 thickly punctured, with some slight impressions in the disk : scutellum short, wide, rounded at the 

 apex : elytra with six elevated granulated lines alternately more pronounced, besides the suture and 

 marginal one separating the epipleura, which meet just above the apex : epipleura granulated : pos- 

 terior legs much longer than the four anterior. 



Mr. Say says of his P. rotunda, that it was the first of that genus found on the New Continent ; 

 that above described furnishes therefore a valuable addition to the American insect Fauna. Africa 

 appears to be the metropolis of the genus, though several species have been found in Russian 

 Tartary.

A pair taken, in the month of April, in Lat. 65°. Taken also in Canada by Dr. 

 Bigsby. 



DESCRIPTION. 



Body dull-black, narrow, naked, minutely punctured. Head nearly round, depressed, porrected; 

 eyes lateral, kidnev-shaped ; nose circumscribed by the segment of a circle ; antenna? a little shorter 

 than the prothorax, joints obconical, four last lentile-shaped : prothorax a little wider than the head, 

 oblong with rounded sides : scutellum rounded at the apex : elytra taken together wider than the 

 prothorax, a little dilated beyond the middle, and then sloping to the apex, which is acute ; very 

 unequal with numerous irregular deep impressions and rugosities, variously separated by a number 

 of elevated lines or obtuse ridges running confusedly in various directions : legs long ; thighs incras- 

 sated ; tibia? and tarsi slender. 



This insect is stated by Fabricius to inhabit a particular kind of Boletus (B. fomentarius L. ) : 

 Gyllenhal says that it inhabits perennial fungi growing upon trees, particularly of the genus Betula. 

 It has not yet been discovered in Britain ; but if attention be directed to these fungi it may very 

 likely at length make its appearance in the list of British insects.
